Figure 3. Pressure vs. Electronic Focal Steering.

Figure 3

The peak-negative focal pressure as a function of electronic focal steering location was measured across a ± 20 mm range of locations centered at the geometric origin. Pressure steering profiles were obtained along the sagittal, coronal and axial dimension. Profile A – C correspond to the normalized pressure profile through skull 1 – 3, respectively, at 250 kHz. Profile D – F correspond to the normalized pressure through skulls 1 – 3, respectively, at 500 kHz.
